Site Report on Physics Plans and ILDG Usage for US Balint Joo Jefferson Lab

Machines used for LQCD in US DOE Facilities –Intrepid ANL –Jaguar (Cray ORNL –Jaguar PF (Cray ORNL –Franklin (Cray NERSC NSF Facilities –Kraken (Cray ORNL –BigBen (Cray PSC –Ranger (Opteron Infiniband TACC Miscellaneous –UBGL LLNL) –New York Blue BNL) USQCD Facilities –QCDOC at BNL –Clusters at FNAL and JLab (jpsi, 7n: Opteron + IB) primarily for analysis

Anisotropic Clover Primary Purpose: –Spectroscopy: Excited States, Resonances, Spin/Parity Identification, Photocouplings –Multi Particle States: Decays Requirements: –Fine temporal extent (control over excited states) –Long temporal extent control contamination from backward propagating states control signal-to-noise ratio –Large volume –High Statistics Most active current consumers: Hadron Spectrum & NPLQCD collaborations

MILC is in the process of completing its AsqTAD contribution to ILDG”

DWF Generation Didn't receive contribution from RBC, –hopefully UK report includes status as part of RBC- UKQCD-LHPC collaboration –Many QCDOC generated configurations available independently of ILDG See the web site for access policies

US ILDG Contributions MILC Continually converting configs and adding them to the Storage Element (SE) at FNAL. –Open access policy: Freely available to ILDG –Mark Up proceeds as Carleton's time allows –Published in MDC when Balint receives it & has time –Sometimes there are configs on SE, but not in MDC/FC Can still get them with GridFTP if location is known Hadron Spectrum collaboration archives configs at JLab. –Anisotropic Clover is available to USQCD, but not freely available worldwide yet. Previous Anisotropic Wilson has been added to ILDG –Publication policy is not stationary. Currently “1 year after first publication” ?

Other sources of US Configurations Gauge Connection –is getting revamped –for more information, see report by Jim Simone later on.
